地球物理方法探测滑坡体结构特征研究现状综述

A review of geophysical detection methods of landslide structure characteristics

浅层地球物理探测技术由于分辨率欠佳,获取的物性参数与工程力学性质之间缺乏关联性,目前还很少被直接应用于滑坡勘查.然而较之常规以钻探为主的勘查方法,该类技术具有安全、快速、经济和无损的特点,加之近年来地球物理探测方法在基础理论研究、仪器设备和信号采集处理等方面都取得了长足的进步,因而其在滑坡体结构特征探测中应用逐渐增多.本文重点调查了近年应用于滑坡体结构特征探测的主流地球物理方法,分析了这些方法自身存在的优势和局限,对其在滑坡体结构探测上的应用研究现状做了归纳和总结.结果表明,国内在该领域研究的系统性、深入程度、手段丰富程度及覆盖密度等方面与国外存在较大差距,需要大力推进地球物理方法在滑坡领域研究中的应用,旨在为与之相关的研究工作提供参考依据.

Shallow geophysical prospecting technique is rarely used in landslide investigation due to the poor resolution of prospecting results and lack of correlation between the physical parameters and mechanical properties of landslide rock and soil. However, geophysical methods are safe, fast, economical and non-destructive compared with traditional drilling technology, and have made great progress in terms of basic theory, equipment, signal sampling and processing in recent years, which are increasingly applied in landslide structure characteristics detection. This paper surveyed the major geophysical prospecting methods applied to detect the structural characteristics of landslide, and analyzed the own advantages and limitations of these methods, and summarized the current research status of geophysical prospecting methods applied in detecting landslide structure in recent years. The results showed that there is a considerable gap with foreign countries in some aspects, such as landslide systematic research, in-depth level of research, the kinds of research means and coverage density, we need to vigorously promote the application research of geophysical methods in landslide, aims to provide a reference basis for other related research work.
